1 INTERNAL-COMBUSTION PUMP.'

ToaZZ whom t may concern.' Beit known that I, CHARLES E. WHITE, a citizen of the United States, residing in the city and county of San Francisco and.

State of California, have invented: a new and useful Improvement in Internal-Comf bustion'Pumps, of which the following is a specification.

My invention relates to internal combustion` pumps wherein parallel vertical pipes are united at the bottom and provided with Specicationof Letters Patent.

the combustion chamber. Fig. 3 is a broken sectional view of the pump disclosing the position of the several parts during the return movement of thev liquid within the pipes. Fig. 4 is a 'view similar toFig. 3 disclosing the position of the several parts a liquid intake valve thereat and a suitable discharge and compression chamber at the top of one pipe and a combustion chamber having intake and exhaust valves and means for operating and controlling thesame at the top of the other pipe, and the objects of my invention are first, to provide parallel vertical pipes wherein the column of liquidv in one pipe counterbalances the column of liquid in the` other pipe for the purpose of reducing the energy required to raise the' liquid in the discharge pipe, second, to keep the discharge no-rmally closed for the purpose of compressing all of the air in the pine above the liquid a portion 'of which'isto bel used for supplying the next combustion charge and also lto use a portion of the air so compressed for the purpose of facilitating the return of the column of liquid to drive the burnt gases from the combustion chamber and to compressfthe combustible charge therein; third, to provide gas intake and exhaust valves that shall be controlled' and operated by the column'of liquidwith in the pipes; and fourth,v to provide an internal combustion pump wherein the liquid shall be drawn'into the pipes when the column of liquid therein movesin either direction. I accomplish these several features by means lof the device illustrated'in the drawings forming a part. of the present specification, wherein like .characters of referencedesignate similar parts throughout other pipe.

the said specication and drawings, and in whichy Figure 1 is a broken elevation, partly in when the return movement of the column of liquid is nearly spent, the gasl exhaust valve being closed and thegas intake valve being 'open to admit a charge of compressed gas. Fig. 5 is a broken detailed view 'on an enlarged scale, of one of the spring latches on the gas intake and exhaust valve stems which engages and operates the means for operating the three-way valve. Fig. 6 is a broken elevation of the mechanism for Patented oct. 19, 11915. Application md November is, 1913. serial No. 801,275.

operating the three-way-valve and Fig. 7 is a view similar to Fig. 6 with the parts shown in position.

I propose to place the combustion chamber nearly level with the lliquid discharge and fill both pipes with liquid so that the column of liquid in one pipe will counterbalance the liquid in the other pipe and consequentlyless.energy7 will be required to raise the level of the liquid a shorter distance to the discharge or the same amount of energy will raise a greater amount of of.. I'The compression pipe liquid the same distance..v Referring'to the drawings, the numeral l.

4is used todesi-gnate a-combustion chamber having a priming pipe 2 and secured to the upper end of theexpansive pipe 3. A return bend 4 having a spring controlled liquid intake valve 5, is secured vto the loweil end of the expansion pipe 3 while'a discharge pipe 6 .is secured to the other outlet' of the said return bend 4 having a compression pipe 7, with a liquid. .discharge 8 therein, secured to the upper portion there-' 1 7 is provided.

` with an annular seat 9 upon which the sleeve section, of the pump within a deep Well, disclosing the pump primed and the pipes ne'arly filled Awith liquid, .the liquidI in one pipe. counter-balancing the [liquid in the Fig. -2 is an enlarged broken 10 rests. The sleeve 10 is provided with a. l .gravity valve 12 the stem of which has a button 14 at the top thereof for the pur .l

pose'of regulating the drop of'the said valve V12. An air intake valve 15 is provided in the top lof the compression pipe 7 for the purpose of admitting air to the compressionchamber C whenl the sleeve l() and the valve. '12 thereinv drop 'toits seat. A pipe 16,1iav-v ing-a check valve 18, connects the compres.- sion chamber C with the receiver 20. A

pipe 21l connects the receiver 20' with the carbureter 22, which opens into thev gas -inpansion'othe'combustible charge within take'port .24. The gas intake yport 24.1% i

provided with a gas intakevalve 26 the stem 28 of which is secured to a `flexible diaphragm 30 within the housing 31. The gasolene tank l33 has a connection 34, controlled by the needle valve 35, to the carbureter 22'.

The combustion vchamber 1 is provided with a gas exhaust port. 40 controlled by the exhaust valve 41, the stem 42 of which is secured to the flexible diaphragm 43 within .the housing 44. A pipe 46, Within the expansion pipe 3, leads to a threeway valve 47 which connects with the pipe 48, to the housing 31, and a pipe 49 which connects the said valve 47 with the housing 44. The cock 50, of the valve 47, is provided with a slotted arm 51, the said slot being engaged by a pin within the approximate center rof a linkV 52, the ends of which are pivotally secured to the lower ends of the levers 53 and 54 which are pivotally secured, as at 55 `and 56 to the housings 31 and 44 respectively. The upper ends 57 and 58 ofthe lev.- ers 53 and 54 are adapted to be engaged by the spring latches 59 and 60 of the stems 28 and 42 respectively. The said latches are controlled by a spring 63 within a slot 62 within each'valve stem in such a manner that the upward movement of either stem will engage the upper end 57 or 58 of the corresponding lever 53 or 54 and movethe same until the said latch passes beyond the arc in which the said end 57 or 58 moves. And

.-carbureter 22 and the said intake port 24.

i Tfhe operation is as follows: By means of thel priming pipe 2 the expansion pipe 3 andthe discharge pipe 6 are nearly lled with liquid until the level thereof reaches approximately the height indicated in Fig. 1 of the drawings, or slightly below the ground vlevel A. A charge of compressed gas is introduced into the combustion chamber and ignited. The expansion of the ignited charge drives the liquid in the expansion pipe 3 downward andV consequently the liquid in the discharge pipe 6 upward. As the liquid in the pipes 3 'and 6 counterbalance each other the static pressure of the liquid in the pipe 6 is compensated or offset by the'static pressure of the liquid in the pipe 3, consequently a comparatively small amount of energy is required to lift the liquidin the. pipe 6 and force the same through the discharge 8 of the compression pipe 7. As the liquid in the pipe 6 Amoves upward it compresses the air above the liquid through the sleeve 10 yuntil it reaches and closes thev ,valve 12 in the said sleeve 10 and raises the said sleeve 10 and valve 12 therein above the discharge 8 at the same' time compressing the` air in the compression chamber C through the pipe 16 and check valve 18 into rllhe rapid passageof the the receiver 20. liquid through the return bend 4 open the liquid intake valve 5 and draws the liquid to be raised into the said return bend 4 and into the discharge pipe 6. The downward movement of the liquid in the expansion pipe 3 acts on the lower end of the pipe 46 and creates. a suction through the said pipe 46 and through the cock 50 .of the valve 47 and pipe 49 to the housing 44. rlhis suction acting on theunder surface of the flexible diaphragm 43 secured within the said housing 44 and to the stem 42 of the exhaust valve 41, has a tendency to draw the said valve 41 downward which it d oes as soon as the expansion of the ignited gases'in the combustion chamber. 1 is completed, and opens the said exhaust valve 41 to the exhaust 40, as illustrated in Fig. 3 of the drawings. When the movement of the column of liquid within the discharge pipe 6 is spent, the'valve 5 closes. At the same time the compressed air within the chamber C vabove the sleeve 10 acts downward on the said sleeve and moves the same onto its seat 9 thereby closing the discharge 8 and opening the valve 12 so that the said pressure of air above the sleeve 10 will be lfree to act on the liquid and force the same downward in the pipe 6 and upward in the pipe 3 thereby driving out the burnt gases from the expansion pipe 3 and the combustion chamber 1 until the liquid reaches the exhaust valve 41 vand closes the same by impact. 1When the compression of the air from the chamber C is spent the continuation oit'` the downward movement of the liquid within the pipe 6 creates a suction within the said compres sion chamber C and opens the air intake valve 15 and draws the air through the said valve 15 into the said compression chamber C and the discharge pipe 6. The rapid passage of the liquid due to the return movement of the'column of liquid within the pipe 6 and return bend 4 causes theliquid intake valve 5 to be again opened, and the liquid to be raised is drawn therethrough and into the expansion pipe 3. When the exhaust Valve 41 is closed by the return movement ot the liquid the upward movement of the stem 42, ofY the said valve 41, causes the latch 60 thereon to engage the end 58 of the lever 54 and, by means of the link 52, which is seV- cured to the arm 51 of the cock 50 within the threeway valve 47, moves the cock 50 so that the passage therein lwill provide communication with the pipe 48 of the housing 31, as illustratedin Figs. 4`and 7 of the drawings.` This locks the water in the housing 44 as the cock 50 iS turned to prevent the escape of-the liquid therefrom, consequently, the exhaust valve'41 can no' be v opened until the cock 50 is again turned to 'I follows: 1st. The compressed charge within 6 through the sleeve 10 andvalve 12 therein; v

the position indicated in Fig. 2 so that'. the

water below the flexible diaphragm 43 can be removed. As the cock 50 is turned, by the closing of the exhaust valve 41, to connect the pipe 48 with the pipe 46 the liquid within the housing 31 is free to flow therefrom through the said pipe 48 and 46 and permit-the opening of the gas intake valve 26 which is o ened by the vcompressed charge within t e intake port 24 and a charge of .gas is thereby delivered into the combustion chamber 1 and further compress by the momentum of the rising column f hquid within the said combustion chamber 1, until the pressure within the said combustion chamber 1 "equals the pressurewlthin the intake vport 24, at which time the. gas intake valve 26 is closed by the action of the rising column of liquid within the expansion pipe 3 acting against the exible diaphragm'30vthrough the pipe 46,v cock 50 valve 47 and pipe48.. As the stem 28 moves'4 upward the spring latch 59 engages the end 57 of the lever 53 and, by means of the link 52 and the arm 51 of the cock 50, turns the cockA 50 so that the connection betweenl the pipe 46 .and the pipe 48 is closed, thereby locklng the l1quid withimthe housin 31 and effectively 'preventing the opening o the gas intake valve 26 until the next charge is required. The upward movement of the stem 28- alsocauses the latch 65 there to engage the latch 66 of the magneto 6T h'ich lias a suitable electrical connection '68 to a spark plug 69 within the combustion chamber 1.

At the end of the upward movement ofthe stem 28 the latch 65 releases the latch 66 and causes a spark in the said spark plug 69.

which ignitesthe compressed charge within the combustion chamber 1 and drives theliq- ,'45 uid through the pipes 3 and Gras hereinbefore described, and the operation of raising the llquid and discharging the same isrepeated Brlefly, the successive' Voperation are as the combustion chamber is ignited and the expansion thereof forces the balanced col!" umn of liquid within the .pipes 3 and 6 t'o.- ward the discharge 8 at the same time opening the liquid intakevalve by suction and 55- drawing liquid into the said pipes and to-\ ward the discharge; compressing the air above the liquid within thedischargepipe closing the valve 12; raising the sleeve 1Q,

thereby opening the discharge 8, and foro.- ing the liquid through the said dlscharge; removing -the liquid from'below the flexible I diaphragm 43f within the -housiiig 44 and thus unlocking and vopening the exhaust valve 41. 2nd. [-`l 1ej momentum of the column'fof liquid beiig spent the valve '5 within the return bend 4 closes; `theoompressed air within the compression. chamber C forces the sleeve 10 and valve 12 therein downward until the sleeve 10 rests upon the seat 9 and closes'the .discharge 8, when the valve 12 is opened :and the compressed air within the chamber C actingI on the column of liquid between the intake valve 5 and valve 12 facilitates the return movement\of the same,

drawing liquid through the valve 45, 'driving the burnt gases from the expansion pipe 3 and combustion chamber 1 through the exhaust port 40; closing the exhaust valve 41, which turns the cock 50 to make yconnection between the housing 31 and the pipe 46, thereby releasing the liquid within the said i housing and unlocking and opening the gas `that the liquid can not escape from the housing B12-thereby locking the said gas' intake valve 26, and preventing the same fromv being' opened until the time for the next charge -to be admitted into J(the 'combustion chamber, 1. Theupward mqvement of lthe stem 28 also causes the latch 65 to engage the latch 66 and `releases the said latch 66 at the same time that the said valve 26` is closed', which releases or opens .the circuit Vandcauses 'a spark to be produced at the spark plug- 69 and ignite the charge within the combustion chamber l.;

It is obvious from the foregoing that-I have provided'improved means for elevating or raising a counterbalanced column of ,liquid which loperates to draw`the liquid to be raised into the discharge pipe; compresses thel air above the hquid; opens the discharge and operates and controls the intake and exhaustl valves of the combustion' chamber, and `draws liquid. through the liquid intake valve when the column of liquid moves in either direction.

The details ofconstruction being so susceptible to variatio I do notfwish to conine myself to the precise construction shown lherein but-rather to avail myself of any modification that-may fall properly within the scope of my invention.
